SIPHON-PIPE HEATER.

SPECIFICATION forming part of Letters Patent No. 356,456, dated January 25, 1887.

Application filed October 17, 1885. Serial No. 180,183. (No model.)

To all whom it may concern.-

Be it known that l, GEORGE E. DIXON, a subject of the Queen of Great Britain, and a citizen ofEngland, and a resident of Chicago, iu the county of Cook Yand State of Illinois, have invented new and useful Improvements in Siphon Pipe Heaters, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which- Figure 1 is a vertical longitudinal section of a heater embodying my improve1nents;'Fig. 2, a vertical transverse section thereof ou line fr. Fig. l; Fig. 3, a plan view of a portion of the upper part of the pipe shown at Fig. 1; Fig. 4, a sectional elevation taken on line 1, Fig, l, looking in direction of dart z.

This invention relates to an improvement in horizont-al steam-pipe heaters; and its nature consists in an inlet steam-pipe, which is so formed in a downwardly-projecting couplinghead that the lower half of said pipe will lie below the inside of the lower tube ofthe heating-pipe, and in a deflecting-plate which is an elongation of and projects out from the up. per portion of the lower tube of the heatingpipe,and is curved downward to form a small passage for the return of dead-steam and water of condensation to the first-mentioned steamsupply pipe, and to form a larger passage for steam to enter the chamber above the pipe.

By ythis means of construction one-half of the periphery ofthe steam-pipe is open at the top thereof, whereby the steam is not obstructed inits passage to the chamber above. Ordinary nipples, which connect the sections of the heater, form round steam-passages from one steam-chamber to the other; hence there is a continuous trough extending transversely through the several heads of the heating-pipes, and each pipe takes steam independent-ly of the other pipes, but all the pipes return the water of condensation into the bottom oi" the steam-supply pipe, in which it returns to the boiler.

It is proper to state that the heater in quespipe.

tion is known as an indirect radiator77 -that is, the heat from it is to be conducted by pipes to Where it is desired, in contradistinction to a radiator which is placed where the heat is required.

AA represent the upper and lower tubes to the heating-pipe; B, the space between them,and Eis whatIterm a steam-chamber.7

S represents a semicircular trough, which is formed in the head C of each single heating- Other single heating-pipes, by hollow nipples R, are connected to form a stack or gate of any desired size. Only one nipple is shown; but as they are all to be of one pattern the illustration is sufficient.

D is the curved dedecting-plate, which directs the steam into the chamber above, as indicated by dart b, and permits dead-steam and water 0f condensation to enter the troughS through the opening a. This construction in practice gives to the heating-pipes a circulating current, as indicated by dartsf, and is such that any one of'the pipes can be replaced by removing the nipples therefrom and making a nipple-connection with a new pipe; or one or more pipes cau be wholly removed from the stack and the remaining pipes connected to form a complete heater.

lHaving thus described myinventiouwhat I claim, and desire to secure by Letters Patent, 1s

An improvement in Siphon-pipe heaters,.
